My family just bought Samsung M31. And i was wondering how can we setting the phone in order to make the screen turn on if there's some notification (for example, WhatsApp Chat) while in lock screen condition?
@NDelanoN: If you go to Settings > Apps > Whatsapp > Notifications > General Notifications > On > Lock Screen > Show Content, this won't turn on the screen, but will increase visibility of incoming notifications. Similarly, go to Settings > Lock Screen > Notifications > On > View Style > Detailed > Show On Always On Display > On. Now, if you prefer, go back to Settings > Lock Screen > Always On Display > On > Show Always, and any notification icons will be visible on screen when you receive them.
